Abstract:

Prognostics and health management is an enabled supporting key technology for ensuring flight safety and twolevel conditionbased maintenance. Data mining is the core implementation technology for engine health status assessment, diagnostics and remaining useful life prediction. First, the military needs and the significance of the PHM technology accompanying with the role of data mining in PHM are briefly reviewed. Then, the key data mining problems and challenges in gas turbine PHM are detailed. Finally, it is argued that the maturing of PHM should be under the collaboration of the computer subject and the aerospace subject.

Key words: prognostics and health management;condition based maintenance;data mining;opportunities and challenges
